binary to "Resource" type

[Former Member]

Hi, do you know how can I change a file from type binary to com.sap.something.Resource? Thanks in advance, Balmer

Hi ,

To convert binary to PDF,

Insert a UI of type IFrame and Create value Attribute called PdfUrl.

Bind PdfUrl to IFrames source.

byte[] pdfContent = wdContext.currentOutput<Element>.getBin_File();

IWDCachedWebResource pdfResource = WDWebResource.getWebResource(pdfContent,WDWebResourceType.PDF);

try

{

wdContext.currentContextElement().setPdfUrl(pdfResource.getURL());

}

catch(Exception e)

{

wdComponentAPI.getMessageManager().reportException(e.getMessage(),true);

}

Hi

Use the following

byte[] data = //Your byte data

IWDResource resource = WDResourceFactory.createInputStream(data)

Hi, it does not work, I get "Type mismatch: cannot convert from IWDInputStream to IWDResource" error. How can I change it? Regards, Blamer

Hi,

But why are using IWDInputStream in between. You can directly IWDResource from the byte content as:

byte[] byteArr = // your content.
IWDResource cache = WDResourceFactory.createCachedResource(byteArr,fileName,WDWebResourceType.JPG_IMAGE);

thanks & regards,

Ok, thanks for help. Could you please advice why this code dont project my picture?

ResultSet rs = stmt.getResultSet();
			while (rs.next()){				
			byte[] b=rs.getBytes(1);
		//IPrivateMyProjectView.IContextElement imageEle=wdContext.createContextElement();
			
		IWDResource cache = WDResourceFactory.createCachedResource(b,"photo",WDWebResourceType.JPG_IMAGE);
				
				if (cache != null) {				
					setImage2(cache.getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal()));
				}		 
			}
		}
		catch(Exception e){
		wdComponentAPI.getMessageManager().reportWarning(e.toString());
	}   

Image2 - context of the Child Image, type String. Regards, Balmer.

Hi,

What is setImage2 here?

Are you sure that you are getting data from the ResultSet?

And you have mapped the source property od your image UI with setImage2?

Else it is perfectly fine.

thanks & regards,

"What is setImage2 here?"

Image2 - Image Child, setImage2 -method. I was able to project picture this way from upload file. This below works fine

IMyProjectView.IContextElement element1 = wdContext.currentContextElement();	
					if (element1.getFileResource1() != null) 
					{
						Object IMessageMyProject = null;	
					IWDResource resource1 = element1.getFileResource1();
		if (element1.getFileResource1() != null) {
			element1.setImage1(element1.getFileResource1().getUrl(WDFileDownloadBehaviour.OPEN_INPLACE.ordinal()));
		 }	

I did equivalent thing like with element1 here but it didnt help

"Are you sure that you are getting data from the ResultSet?"

yes

"And you have mapped the source property od your image UI with setImage2?"

since I made it working in upload I think yes

Thanks for help and looking for a reply, Balmer.

To get the URL of the resource, you can just use toString().

IWDResource image = WDResourceFactory.createCachedResource(b,"photo",WDWebResourceType.JPG_IMAGE);
String url = image.toString();
